Topics (interest preferences)

Interest categories on a mailing list. Subscribers pick which ones they want; you target campaigns at them.

Topics split one mailing list into smaller interest groups. Subscribers sign up once, then pick which topics they actually want.

Setup

Create a topic in Contacts → Lists → Topics (just a name).
Link the topic to one or more mailing lists.
On your subscribe form, expose the topics so new subscribers can pick.
Build a campaign segment that targets one or more topics, and send only to interested contacts.

Why this helps
When subscribers pick what they get, fewer of them unsubscribe — usually without you having to change the campaigns themselves.

Do contacts choose their own topics?

Yes — topics are subscription preferences the contact opts into on a subscribe form. That opt-in is the consent record that makes topic-targeted campaigns legitimate.

Can I assign a topic to a contact manually?

You can, via the contact's edit screen or in bulk via the overview, but be aware that doing so does not generate a consent record. Use tags instead for purely internal grouping you assign yourself.

How do contacts unsubscribe from a single topic?

Every campaign's footer includes a preferences link where the recipient can untick individual topics rather than unsubscribing from everything. Granular control reduces full unsubscribes.
